Description

Technical Field

[0001] The utility model relates to an electric control device, in particular to an electric control device for centralized conveying of strip cartons, belonging to the technical field of cigarette production. Background Technique

[0002] Strip cigarettes are a form of cigarette packaging produced and sold by tobacco companies, usually consisting of multiple cigarette boxes to form a standard strip carton. As one of the main sales forms of cigarettes, strip cigarettes are widely used in channels such as retail, wholesale, and distribution. In the sales process, the packaging design and brand image of strip cigarettes also play an important role in promotion.

[0003] In the packaging production line of the strip cigarette industry, the centralized conveying electric control device is an electric control system specifically designed to control the centralized, efficient, and automated conveying of cigarette boxes on the conveyor line, mainly realizing important control functions such as automated conveying, speed control, and positioning control. By controlling the motors of the conveyor belt or chain, the continuous and stable conveying of cigarette boxes is achieved. It can also accurately adjust the conveying speed according to the requirements of the packaging machine to ensure that the cigarette boxes can enter the packaging machine at a predetermined rhythm and time interval, avoiding congestion and waiting.

[0004] In the working process of the existing centralized conveying electric control system, there is a lack of positioning and deviation correction for strip cigarettes. When the strip cigarettes are conveyed to the packaging station, the position of the strip cigarettes will shift. The shift of the position of the strip cigarettes causes the packaging materials to not be able to accurately align with the strip cigarettes, resulting in packaging misalignment. This not only affects the appearance quality of the product but also makes the packaging unable to effectively protect the strip cigarettes, increasing the risk of damage during transportation and storage. For this reason, an electric control device for centralized conveying of strip cartons is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electric control device for centralized conveying of strip cartons to solve one of the problems raised in the above background technique.

[0006] The utility model is implemented by the following technical solution: An electric control device for centralized conveying of strip cartons includes a conveyor, and a positioning and deviation correction assembly is installed on the frame of the conveyor;

[0007] The positioning and deviation correction assembly includes a support frame, a deviation correction cylinder, a lifting frame, a deviation correction frame, two contact wheels, a linkage frame, a tension spring, a slider, and two limit rods;

[0008] The support frame is fixedly connected to the upper surface of the conveyor frame. The deviation rectifying cylinder is installed on the upper surface of the support frame. The top of the deviation rectifying frame is rotatably connected to one side of the lifting frame. An electromagnet is installed on the lower surface of the lifting frame. The two contact wheels are symmetrically installed on one side of the deviation rectifying frame. The slider is slidably connected to the outer side walls of the two limiting rods. The tension spring is sleeved on the outer side walls of the limiting rods. One end of the linkage frame is rotatably connected to the lower surface of the slider, and the other end of the linkage frame is rotatably connected to the deviation rectifying frame. A suction block is fixedly connected to the lower surface of the slider.

[0009] As a further preference of this technical solution: A chute is provided on the lower surface of the lifting frame, and both ends of the limiting rod are symmetrically and fixedly connected to the inner side wall of the chute.

[0010] As a further preference of this technical solution: The slider is slidably connected to the inner side wall of the chute. One end of the tension spring is fixedly connected to the slider, and the other end of the tension spring is fixedly connected to the lifting frame.

[0011] As a further preference of this technical solution: The electromagnet and the suction block are magnetically adsorbed and attached to each other. The cylinder shaft of the deviation rectifying cylinder is fixedly connected to the upper surface of the lifting frame.

[0012] As a further preference of this technical solution: Two guide rods are symmetrically and fixedly connected to the upper surface of the lifting frame, and the guide rods are slidably connected to the inside of the support frame.

[0013] As a further preference of this technical solution: A monitoring frame is installed on one side of the support frame, and a speed sensor is installed inside the monitoring frame.

[0015] As a further preference of this technical solution: The deviation rectifying frame is located above the conveyor.

[0016] Advantages of the present utility model: By pushing the lifting frame downward through the deviation rectifying cylinder, the deviation rectifying frame can be located in front of the moving direction of the cigarette carton. As the cigarette carton moves, the cigarette carton contacts the contact wheels on the deviation rectifying frame. Since the cigarette carton is strip-shaped, the side of the cigarette carton remains parallel to the deviation rectifying frame as the conveyor conveys, thereby completing the deviation rectification of the cigarette carton. When the conveyor transports the deviation-rectified cigarette carton to the packaging station, the packaging material can be accurately aligned with the cigarette carton, improving the packaging quality of the cigarette carton. When the deviation rectification and positioning of the cigarette carton are completed, the electromagnet is powered off, and under the pulling of the tension spring, the deviation rectifying frame moves away from the cigarette carton. At this time, the conveyor moves the cigarette carton to the packaging station, and the deviation rectifying action is completed. Description of the Drawings

[0025] Embodiment

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a strip box centralized conveying electric control device, including a conveyor 31, and a positioning and deviation correction assembly 101 is installed on the frame of the conveyor 31;

[0027] The conveyor 31 is used to continuously and stably convey cigarette boxes. A packaging machine is arranged at the end of the conveyor 31. Under the conveyance of the conveyor 31, the cigarette boxes can enter the packaging machine according to a predetermined rhythm and time interval.

[0028] The positioning and deviation correction assembly 101 includes a support frame 11, a deviation correction cylinder 13, a lifting frame 14, a deviation correction frame 15, two contact wheels 18, a linkage frame 19, a tension spring 20, a slider 21, and two limit rods 23.

[0029] The support frame 11 is fixedly connected to the upper surface of the frame of the conveyor 31. The deviation correction cylinder 13 is installed on the upper surface of the support frame 11. The top of the deviation correction frame 15 is rotatably connected to one side of the lifting frame 14. An electromagnet 17 is installed on the lower surface of the lifting frame 14. The two contact wheels 18 are symmetrically installed on one side of the deviation correction frame 15. The slider 21 is slidably connected to the outer side walls of the two limit rods 23. The tension spring 20 is sleeved on the outer side walls of the limit rods 23. One end of the linkage frame 19 is rotatably connected to the lower surface of the slider 21. The other end of the linkage frame 19 is rotatably connected to the deviation correction frame 15. A suction block 22 is fixedly connected to the lower surface of the slider 21. The deviation correction frame 15 is located above the conveyor 31.

[0030] The positioning and deviation correction assembly 101 is used to realize the positioning and deviation correction of strip cigarette boxes. A vision sensor is installed on the support frame 11 to detect whether there is a position deviation of the strip cigarette boxes.

[0031] When deviation correction is required, the lifting frame 14 is pushed downward by the deviation correction cylinder 13. The lifting frame 14 drives the deviation correction frame 15 to move downward, so that the deviation correction frame 15 can be located in front of the moving direction of the strip cigarette boxes. As the strip cigarette boxes move, the strip cigarette boxes come into contact with the contact wheels 18 on the deviation correction frame 15. Since the strip cigarette boxes are in strip shape, along with the conveyance of the conveyor 31, the side edges of the strip cigarette boxes are kept parallel to the deviation correction frame 15, thus completing the deviation correction of the strip cigarette boxes.

[0032] In this embodiment, specifically: a chute 16 is formed on the lower surface of the lifting frame 14. The two ends of the limit rod 23 are symmetrically and fixedly connected to the inner side walls of the chute 16. The slider 21 is slidably connected to the inner side walls of the chute 16. One end of the tension spring 20 is fixedly connected to the slider 21. The other end of the tension spring 20 is fixedly connected to the lifting frame 14. When the deviation correction and positioning of the strip cigarette boxes are completed, the slider 21 is pulled by the tension spring 20 to move, and the slider 21 resets. At the same time, the slider 21 pushes the deviation correction frame 15 to rotate through the linkage frame 19. At this time, under the conveyance of the conveyor 31, the strip cigarette boxes move to the packaging station.

[0033] In this embodiment, specifically: the electromagnet 17 and the suction block 22 are adsorbed and fitted by magnetic force. The cylinder shaft of the deviation correction cylinder 13 is fixedly connected to the upper surface of the lifting frame 14. By adsorbing the suction block 22 with the electromagnet 17, the position of the deviation correction frame 15 can be fixed for deviation correction operation.

[0034] In this embodiment, specifically: Two guide rods 12 are symmetrically and fixedly connected to the upper surface of the lifting frame 14. The guide rods 12 are slidably connected to the inside of the support frame 11. The guide rods 12 can play a limiting role to enable the lifting frame 14 to lift vertically.

[0035] In this embodiment, specifically: A monitoring frame 24 is installed on one side of the support frame 11. A speed sensor 25 is installed inside the monitoring frame 24. The speed sensor 25 can monitor the moving speed of the conveyor belt in real time. When the speed exceeds the rated value, a signal is sent to the PLC controller 28, and the PLC controller 28 adjusts the conveying speed of the conveyor 31.

[0036] In this embodiment, specifically: An electric control box 26 is installed on the front surface of the support frame 11. A relay 27 and a PLC controller 28 are installed inside the electric control box 26. The signal end of the PLC controller 28 is respectively connected to the signal ends of the deviation rectifying cylinder 13, the electromagnet 17, the speed sensor 25, and the conveyor 31 through the relay 27;

[0037] The model of the PLC controller 28 is: OHR-PR10, and the model of the speed sensor 25 is: Hal-18.

[0038] During operation or in terms of the structural principle, when in use, the cigarette cartons are placed on the conveyor 31, and the conveyor 31 conveys the cigarette cartons. When deviation rectification is required, the deviation rectifying cylinder 13 is used to push the lifting frame 14 downward. The lifting frame 14 drives the deviation rectifying frame 15 downward, so that the deviation rectifying frame 15 can be located in front of the moving direction of the cigarette cartons. As the cigarette cartons move, the cigarette cartons come into contact with the contact wheels 18 on the deviation rectifying frame 15. Since the cigarette cartons are in a strip shape, as the conveyor 31 conveys, the side of the cigarette cartons remains parallel to the deviation rectifying frame 15, thus completing the deviation rectification of the cigarette cartons. When the deviation rectification and positioning of the cigarette cartons are completed, the electromagnet 17 is powered off. At this time, under the pulling of the tension spring 20, the slider 21 slides along the limiting rod 23 and resets. When the slider 21 moves, it pushes the deviation rectifying frame 15 to rotate through the linkage frame 19. Then the deviation rectifying frame 15 moves away from the cigarette cartons. At this time, under the conveying of the conveyor 31, the cigarette cartons move to the packaging station, and the deviation rectifying cylinder 13 drives the lifting frame 14 to reset for the next deviation rectification operation.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
